I agree with @DonFletcher - it sounds like a Brushtail Possum. Have a listen at https://wildambience.com/wildlife-sounds/common-brushtail-possum/?srsltid=AfmBOoqmM4d5Zb3Ve0K_dUXau_o-cap3CBHsUAWprxcybcxx3YPLhba7
Hi @Frecko, I'm not good with sounds and I don't really know what this is but to me it sounds a bit like like a Brush Tailed Possum. Maybe other mammal moderators will chip in with their opinions.
Ring Tailed Poss is also in area but its dental arch appears more rounded (wider in relation to length) and its upper jaw does not have large gaps between teeth 3 to 6, as seen here, which are typical of Trichosurus.
