How does tax work - VAT and GST

Just to chime in with a quick question regarding GST on Australian OFN, it’s now applicable to products, but I can’t seem to find a way to apply it to enterprise fees. I noted that tax on fees was mentioned above, but wasn’t sure if it was in place as part of the latest update? (if so, can someone point me in the right direction?)

For instance, any delivery fees we would charge, would need to include GST (and I guess show that in the customer order and invoices - as noted in the set-up at the top of this discussion “Each of the fees charged, marked as “(inc. GST)” when GST is included in it”)
