" House sale in Maroochy Waters "

Thank you Grant for your expert advice on the recent sale of our property at 49 Schirrmann Drive, Maroochydore. Grant was very helpful and he is a true professional in every sense of the word, and he was always available to speak with if we had any queries.


" Excellent Agent "

Having purchased a unit through Grant we engaged him to sell our existing unit.  This was due to his professiionalisim, integrity and excellent communication skills.  The process was stress free and we achieved a sale in short time frame and above the price I was realistically expecting.  Grant does not put any pressure on you and I would highly recommend him above all other agents I have dealt with.

" Great Bloke, that's become a fabulous Agent. "

Grant approached us about a unit, that he had heard we liked. We confirmed that we would be interested if he could get the other party to the table. Knowing the unit had been on the market 2 years prior and the vendor was a tough businessman, we didn't pin our hopes to high that he would pull it off. We actually thought he had Buckleys, but He did it! Within 2 weeks we had the contract signed and settled in 30 days.Every attribute of Grants manner in the way he conducted himself on a personal and a professional was outstanding. He conducted the sale on the level of a professional friend not solely as an agent, which suited us. I ve dealt with my fair share of stock and station agents in my time and are very wary!I will do business with Grant again, if the opportunity arises and He and his wife will become good friends of ours. Not much more I can say but, that if I wanted to sell or buy on the coast, Grants number would be the first I would dial.....

" “Highly effective real estate agent” "

We were extremely fortunate to have Grant Whisker’s professional service and excellent communications working on our property transaction for our first property purchase in Australia. Grant was extremely helpful and knowledgeable in assisting us through this process to ensure a positive outcome for this transaction. We live in NZ and Grant assisted us through a more complicated overseas transaction process which was very helpful, and we are delighted with the outcome. We highly recommend Grant to anyone considering a property transaction.

" “Thanks Grant” "

  We really appreciated Grant's helpful professional manner. He was always friendly and approachable. Our purchase was not straight forward, and it was refreshing to work with an agent with such a "can do" attitude. Thanks again Grant.

" “Highly Recommend this Agent!” "

We have just sold our property and couldn't be happier with Grant. I would highly recommend him to anybody looking and would certainly use him again in the future. Grant was so easy to deal with from the get go. His communication was like nothing we have received before, we always felt completely in the loop by knowing exactly where we were at along the way. Grant is honest, reliable and just a genuine person to deal with. He also got a record selling price for our property, which was the icing on the cake for us!

" Grant got the job done "

I met Grant quite by chance, so when I discovered he was an estate agent I had a job for him. I had been asked by an elderly couple to assist in selling the family home. Grants advice and market knowledge was very helpful. in a short time, he found a buyer and showed extreme patience and professionalism as the sale progressed through to completion. the owners and I were very happy with the outcome...Grant, thanks again.

Peter Chadband


Grant was very diligent and persistent in the marketing of our property, which was obviously in a specialised market. Communication was consistent and to the point - even taking into consideration his broad Kiwi accent!!!!

Paul Wray

" Solid Outcome "

Grant produced a solid outcome and was very professional and dedicated in his work for me.

Peter McMillan

" Awesome Result "

Grants knowledge when it came to marketing my property was impressive and successful. Grant knew what inquiries were from genuine buyers with the ability to purchase this category of property. Because Grant knew how to market my property, I would think the buyers would have had a pleasant experience purchasing it as well. My contract price was very close to my asking price with no silly offers put forward, again due to the correct marketing and the buyer feeling comfortable with the correct professional information being given to them and to myself when Grant initially inspected my property. I would highly recommend Grant to any Seller or Buyer. I would not use any other agent on the Sunshine Coast now. Thank you, Grant.

" “A true Professional” "

We have dealt with many agents over the years and we have found Grant to be best we have ever dealt with. He is genuine, keen to oblige, knowledgeable and very professional in every aspect. His communication is outstanding. I feel this is why our property sold for asking price within 4 days of being on the market.

Comparing real estate agents, it was a delight to have such an honest, genuine and willing salesperson such as yourself. We left our trust in your hands and you delivered. Once again, thank you Grant. Paul Keys

We meet Grant on our first Open Home visit to Unit 12. Easy going, no stress, just relax, were the first characteristics that were on show. But he did know his stuff when talking about property along Parkyn Parade. He lives there and has made it his business to know the people, the properties, the prices and he shows his passion for the area. The purchase went very smoothly, the communication was excellent, Grant even offered to help shift our furniture in. Buying and selling can be a very stressful time, do yourself a big favour and contact the most relaxed guy in Mooloolaba.  

Kerry & Barbara O'Donnell


I found Grant up to date with all aspects of selling property in the area. He was always informative, and kept me appraised of what was happening at every point in the sale. As I was hard to contact, being overseas for most of the sale, he used appropriate communication methods to inform me of important events and directions. His suggestions were always well thought out and gave me a number options to choose from. Having sold a number of properties throughout Australia over the years, I could safely say that Grant was the most professional and approachable agent I have worked with.    

Michael Lynch


In all aspects of our purchase Grant was a pleasure to deal with and often went above and beyond to be helpful. We would definitely recommend him to others  

David and Jennifer Beal


Grant is enthusiastic and very hard working. He has great ethics and gave me fantastic support throughout the entire process. I would highly recommend Grant and his very professional team of stylist, photographer and admin. His advertising strategies Worked a treat and resulted in a sale after 1-week Thankyou Grant

" The Only Agent to Use "

From our first conversation with Grant he showed a passion for living on the Spit, which combined with his personal knowledge of the area, he lives there after all, made it clear he was the only agent to use in the sale of our unit. He in fact performed well beyond our expectations and he kept us informed on all issues and activities on a regular basis and got the marketing tasks and first open for inspection off to a cracking start. Within 4 weeks he had found the new owners and negotiated a top offer from them which exceeded all our initial expectations. His friendly, approachable nature, genuine interest, marketing capability, outright honesty and depth of experience, all make him the leader that he is when it comes to selling property. Thank you, Grant.

Having owned an apartment at Lahaina in Parkyn Parade Mooloolaba for over twenty years and as the kids had moved on, we decided that the time had come to sell. We carefully reviewed the credentials of local agents and decided upon one located in Maroochydore which seemed to have the runs on the board. Twelve months later there was only one offer which did not meet our expectations. Out of the blue we received an approach from Grant Whisker of Define Property who resided opposite our property in Parkyn Parade. Grant assured us that he could successfully market the property in the short term. We agreed to an exclusive listing for 45 days. Imagine our surprise and appreciation when he had an offer on the table, $20,000 better than that negotiated by the original agent within ten days. Well done Grant. We sincerely appreciate your efforts on our behalf. We have no hesitation in recommending Grant to anyone contemplating a sale in the region. Phillip & Ronelle Ellick
