You could always try to find some form of “bonus”, like the first hour has a -20% discount for new customers, or for every 9 hours you get one free. I don’t know how aussie dollars translate, but if you feel like it’s a reasonable price, especially if it includes driving, insurance, proper taxation etc, I think it’s fair. Here dogs are often walked by schoolchildren (for free or cheap), but it has some risks, is dangerous if they’re a single kid for 3-4 big dogs, and of course is outside of any taxation or insurance.
I would heavily lean on the “premium” aspect of your qualifications. See how can you include your knowledge in training and qualifications (certifications?) into it. Also maybe make sure it’s clear that you include travel etc. Show it’s more than a walk. Don’t lower your pricing unless you’re offering worse service. (like having travel costs be paid separately, or whatever)
Not sure why the discussion is “they’re censoring AI!” rather than “they’re censoring adult material!”. Payment processors banning adult content is nothing new. I’m not saying I agree with it, but it’s strange me that chat AI/GPTs should get an exception, when everyone else (non text AI or human) are affected by these measures on the daily.
