Reliable and professional

Aqua Pro has been servicing and maintaining my game boat “Smartbill” now for over 15 years. I find them reliable, professional and exhibit a lot of knowledge and experience with all things marine mechanical associated with my diesel inboards. Aqua Pro ensures my game boat Smartbill is always performing at optimum level and always ready for any offshore fishing tournaments we choose to enter. I highly recommend Aqua Pro, in particular Brett Thorp, who I find pleasant to deal with, is honest and charges fairly for any work he performs.

Boating is a way of life for many Australians, with about 2.5 million, approximately 10% of the population, having direct access to boats, and this number continues to grow year after year. And whilst taking to the water brings great pleasure to devotees, boat maintenance and upkeep is an aspect of this lifestyle that demands serious consideration. Whether you are a weekend recreational fisherman or operate a commercial boating enterprise, safety on the water must always be your first concern, and what price is peace of mind! – but after that there is little doubt that the appearance of a boat and the degree of comfort that it affords are also high on the list of requirements. 

Aqua Pro Marine Engineering, led by Brett Thorp and based in NSW have been keeping boats running safely and efficiently whilst also maintaining their pristine looks for over two decades, in which time they have also built up an extensive network of professional contacts within the boating world.

A refusal to accept second best and a critical eye for details are factors that set Aqua Pro apart from competitors and whether you have a luxury yacht such as a Riviera requiring a service in Port Stephens, a Maritomo for service in Newcastle or something far more modest, you will still receive the same exemplary level of service that will give you the peace of mind necessary when you set sail.
