That's exciting, always worthy of a road trip!
You're right on the multiple source of income thing, complex, but diversification is important. I get the impression you do your tax yourself, not something I'd be able to do due to the complexity: Businesses, income streams and so on. I tax deduct the accounting costs in the following year's tax though so it's ok.
I don't know if you're doing this already. But if you declare/include your profits/income from Hive, maybe you can ask your accountant about additional deductibles. I've heard that YT vloggers can write their travel to different countries as an expense since they made a video of it.
