@kmakm Oh - would need to be indoor as temperature required for hydrotherapy I gather is higher than a normal heated pool and thus expensive to run.
Maybe with all your brilliant sports stadiums ( my sons did basketball tournaments in Melbourne) some agitation on the health front needs to be done esp based on what @Zoffiel is describing in regional Victoria.
I still reckon your public hospitals would have under-utilised capacity in their hydrotherapy pools that could be used by a community organisation like the YWCA delivering a rehabilitation service for free to breast cancer people 1 hour per week.
