2002Greg experiments with breaking waves produced by boat wake in a river. He ponders how to capture these waves – increase their size and ride them. He wonders if a large moving hull could be used to generate waves capable of being surfed, especially if the hull was running alongside a channel, thereby making a wave pool.

2003In April, Greg and his brother Dan lodge a patent application for a circular wave pool. In November, Greg and his brother Monty release an avant-garde surf film featuring perfect tubing waves, created by boat waves, breaking along the bank of a river.

2004Greg lodges a patent application for his wave pool design. Liquid Time received the Cinematography Award at the 2004 Saint Jean de Luz Surf Film Festival.

2005Greg rides 1 metre high waves produced by a fishing trawler in a river. The rides are up to 2 minutes long, and are only limited by the length of the river bank.

2006Tow tank testing and computer modeling of the design commence at Delft University of Technology (TUDelft), Netherlands under supervision of Greg and his engineer. Greg and his first client sign a Memorandum of Understanding to develop the first pool. Greg teams with Michael Lee Designs, a leading Theme and Water park design and construction company in the USA.

2007 Liquid Time Pty Ltd is formed. Liquid Time Pty Ltd releases a DVD showing the 3D model of the wave pool and videos of the river surfing. Liquid Time Pty Ltd releases the second river surfing DVD.

2008Liquid Time Pty Ltd commences a research program with the Australian Maritime College (AMC) and TUDelft.

2009Liquid Time Pty Ltd, AMC and TUDelft are awarded an Australian Research Council (ARC) Research grant.

2010Liquid Time Pty Ltd, AMC and TUDelft construct and test a 10 metre scale model constructed at AMC. Billabong releases video of the river surfing.

2011Liquid Time Pty Ltd create two barreling waves from each wave generator. Full US patent awarded.
