Pond size is around 15,000litres.
Both those companies don't ship to Australia anymore, have emailed everyone. I looked at a synergy combi too but they said import fees are too high so won't send. I mean it's narrowed my choices haha.
I have a Draco Solum 16 on a ~14K litre pond, running airlifts for about 18-20K litres per hour. The drum is rated at 16K but I run it at its limit and some. I would say you want to take drums figures not at the clean water throughput but factor in both waste and biofilm restrictions and use a figure of 60% that rating for your selection. So a Solum 25 or even another brand with a little more at 35-45K litres an hour would be the size of drum I'd be looking at.
I have used the Draco in direct UK sun for over a year before switching the location inside and out of the sun. Aus UV levels are far higher so I would consider that into your purchase decision (I didn't have an issue except my rubber boots degraded I used to contact the pipe to the drum inlets in direct sun degraded. The plastic of the Draco seemed fine. The Draco control box I would NOT put in directly outside - I've had one control box full of water thus getting a replacement from Draco. I would advise putting that under shelter or in a weather proof control box along with any other electrics.
You can replace the drum mesh - mine is the factory 57 micron mesh but others here in the UK have switched out for 70 micron without any real issues. Outside ponds get more mess to deal with which makes that a good 'upgrade' for little impact on the pond.
Eco pond: ~14,000l pond, 20,000lph airlifts, XP80, Drum & Anoxic filtration, No water pump - total power 58 Watts.
