Wedding venue location help

Hi everyone I’m struggling to find an affordable outdoor venue and would love your recommendations. I’m after a forest/bush vibe within about 2 hours of Sydney, with a budget under $5,000 for site/venue hire. A campground or somewhere guests can stay overnight would be a huge bonus. Does anyone have suggestions or places they’ve used? Small, unique spots and function rooms in non-typical wedding places are perfect doesn’t have to be a traditional venue, just outdoors and pretty. Thanks so much!
