A NEW CONCEPT IN WAVE GENERATION TECHNOLOGY
We are currently refining the design and will require investment to complete the full scale design and feasibility for the first site. Suitable sites are being considered as owner-operated or partner sites, under licence. Due to the productivity advantage and access to multiple activities in the one location, a Surf Lakes venue will provide substantial returns as an operation, as well as commercial development possibilities.

The recent developments by wave pool innovators all have a lot of merit and I look forward to riding them as well. Our aim is to produce larger waves with more rides per hour and greater variety, at the same time. Other configurations also focus more on “point break” style waves which can create longer rides than our method.
However, we will produce large peaks or “A-frames” that break left and right, so it will be the most realistic experience with two surfers dropping either direction into the barrel. This will make Surf Lakes an amazing “stand-alone” venue and we could also be complementary to the point break style wave pools. We use a downward force on the water so create more of a trough in front of the wave, such that the wave shape resembles natural waves more closely.
A key metric for wave pools is that the facility needs high productivity to be profitable and therefore attract funding to be built. Other methods produce typically 120-500 rides per hour verses over 2000 rides per hour for Surf Lakes when operating. This is a massive advantage and we aim to have hundreds of surfers at a time and thousands of swimmers at the same time, all enjoying their portion of the waves. By fixing the location of the peaks, we also create a predictable, safer environment which is easier to manage for all.
For surfers, it means more waves and more barrels. For investors, it means more people and higher returns. Everyone gets a break.
Waves are quite predictable in that they do the same thing every time, when produced the same way every time. The ocean is infinitely variable, which is a big part of it’s beauty. We cannot compete with the natural beauty of the ocean but we can provide consistent waves day and night. Deliberate design, modelling and testing allows us to accurately predict wave behaviour at every point in the facility. We can then choose optimum sequences to provide the best outcomes for everyone.
Even the wind direction and strength is not a problem, as the design allows for “offshore winds” at half of the breaks, no matter the wind direction. The waves will be smoothed from the central mechanism and thus chop is minimised, regardless of wind conditions. Each break can have a different bathymetry, allowing for variability of the breaks and consistency within each break. The size and speed of the swell can be altered, creating further variability for the surfers.
Perfect waves – every day and every night.
The patent pending wave generation technique creates large surges of up to 4m high near the centre. This reduces to the 2m swell at the first reef which becomes a 1.2m swell at the end of the pool. Similar ratios apply for smaller sets of waves.
The result is a powerful peak that wraps/straightens around the reef and peels in both directions, creating a left hand and right hand wave. The shore break configuration can vary from fun closeout to dissipating into a “bay” depending on design. This action is repeated at each side/end of the pool, resulting in four peaks, thus eight breaks at a time.
• Productivity – more than 2000 rides per hour, in sets of waves
• Left and right hand waves at the same time
• Simultaneous variety of waves, – size and shape
• Multiple shorelines for access, swimmers and spectators
• Consistent break locations for safe and efficient operation
• Smoother waves with each shoreline used to reduce chop and backwash
Absolutely. The process for swell generation is the same at any size, but the energy requirement increases dramatically of course. The 1:10 scale model proves the concept and we know that we can alter the reef configurations (bathymetry) to create a variety of waves. We can also alter the swell size, speed and period to create different effects. During the testing we had a variety of shapes produced, including gentle rollers, barrels and slabs so we can create any shape wave, within the limits of wave energy produced.
The larger prototype has helped us refine the parameters of design (reef depth, pitch, peel angle, etc) so that we can guarantee the wave shapes at each reef. We are in the process of refining the force delivery with more physical testing and CFD Modelling, so that we produce an optimised solution.
We are confident that the waves will scale to full size and create an incredible location, with waves for all abilities. Everyone gets a break.
Surveys completed for Surfing Australia indicate that 1 in 10 Australians like to surf, with 3 in 10 wanting to learn to surf. For the Brisbane area alone, this equates to over 800,000 people who would use Surf Lakes regularly.
Our conservative operating budget requires circa 315,000 people to visit Surf Lakes only once each year, to provide annual returns of over 25% on $20M capital expenditure. Surfers will not be satisfied to visit once per year and are more likely to visit once per month or more, and many will take an annual membership. Night surfing will be particularly attractive for most of the year in Brisbane, as busy people can fit surfing into their schedule by having a session after hours. When including visitors from the Gold Coast, Sunshine coast and other national locations, there will be no shortage of a market, without even considering the growing number of international tourists to SE Qld. The facility is multi-faceted and appealing not just for surfers but it will become a recreational attraction for people of all ages.
In short – no. One very exciting option is to mount/float the facility in a large lake, bay or open ocean. Due to the nature of the process, we believe it will work just as well and there may even be some advantages by doing this. At a suitable time we will also test a scale version of this option to confirm our thinking.
This possibility certainly lights up the imagination and could broaden the location possibilities. I love the idea of tapping into solar, wind and wave/tide power, to generate perfect surfing waves and we will incorporate renewable energy solutions in each location.
The global market is enormous. Every city of over 1M people could sustain a Surf Lakes stadium and other business models could be considered for areas of lower population density.
Surfing is growing in popularity every day and this advancement will create an entire new market for surfing related products and services, as surfing moves into the mainstream. Having Surf Lakes established in Queensland before the 2018 Commonwealth Games would allow for global attention, as we could host surfing as a “demonstration sport” and create immediate global credibility.
Ongoing maintenance requirements will be a major consideration in the final design, such that it may be wiser to choose the higher capital cost to reduce the ongoing maintenance cost. Minimising downtime for maintenance is a major consideration for an operation that aims to provide waves seven days per week. Composite materials are being considered where possible to minimise corrosion and we will most likely use concrete reinforced with Helix micro-rebar to strengthen the concrete, minimise cracking and reduce construction costs. The decision to use salt or fresh water will play a major role in design of the maintenance program. Thankfully, we have an expert team who are more than capable to provide the most reliable, cost effective solutions.
The lake itself will require a footprint of circa 220m x 180m, plus surrounding stadiums/terraces and development. It can be scaled up or down depending on the requirements. The complete facility may require the equivalent of 8-10 hectares, depending upon the availability of shared infrastructure (such as car parking) at the chosen site. The central tower could be up to 25m high at full scale and creates another recreation asset as it can be used for multiple purposes such as a viewing tower, rock climbing wall, entry point for surfers, solar and wind power generation. There are many design options as the pool edges can be shaped in a variety of ways, incorporating swimming areas, body-surfing, scuba, reef snorkeling, etc
We aim to provide clean, healthy fun for people of all ages. Everyone Gets a Break!
