I don't even really mean this in the sense that some accents may be harder to understand when speaking English, but in the sense that my accent has always been out of place.
I'm an Asian-Australian in the sense that I was born to a 100% Filipino family who moved to Australia when I was very young from England, and obtained citizenship. I have lived a majority of my life here in Brisbane, and I would sooner call it home before Bacolod City or (god forbid) Birmingham.
I have never, ever, ever had an Aussie accent. For as long as I've known, my accent has been the thickest "general American" accent ever. Only somewhat recently I learned I have the "International School Accent", which is a vaguely American sounding accent apparently picked up by students studying at international schools, something I never did.
I think the leading theory is that while I maintain some Australian pronunciations ("Aussie", "Australia", "mum", etc.) due to being around Aussies my whole life, I mostly speak "American" due to the strong amount of American media I was watching when I was still learning English (and as a consequence forgetting Tagalog sadly). Kinda cool!
To this day people will ask me "Are you a Yank?". I'm just happy to have such a common conversation starter.
