Where can I post to get advice about planting a site?

Hi all, sorry I'm fairly new to gardening/permaculture and basically I would love to post a pic of my backyard to a subreddit and have some people chuck some ideas at me. Can't afford to hire a pro so this is the best I'm gonna get!

Do y'all have any idea where I could post something like that?

Fyi I'm in Sydney Australia if it makes a difference. Would love to have some edible stuff in the backyard to save on groceries.
