DO's branding and a lot of their offering is pretty good, but their locations for non-US customers are much worse than many of their competitors. For instance (and a particular point for me), they still don't have any presence in Australia after over half a decade of it being marked as "under review" on their customer feedback page.
Having geographical locations to back up the quality of the offering is a step forward IMO.
Most likely Telstra (40% market share telco) charge too much for peering network traffic in Australia? Same as how Google Cloud free tier excludes only China and Australia.
Vultr has a POP in Sydney and seem to manage just fine, offering plans similar to DO. I like DO but as I'm based in New Zealand, it's a no brainer to go with Vultr due to their Sydney POP.
