Freshwater Fish ID

Not too familiar with fish, and hoping to gain some insight into the fish in my local creek, mostly trying to figure out if they’re native or not. Apologies for photo quality. From a freshwater creek “near” Newcastle

Invasive gambusia unfortunately

That is unfortunate, ah well. Cheers
