Many Australian flags still adopt a blue ensign as their own flag, but Northern Territory and Australian Capital Territory successfully changed its own flag to a common pattern, often called "Australian pale". There's even a campaign to change all Australian flags to that pattern. To understand better what I'm saying, look at current Tasmanian flag:
A red lion is so generic that it could be used by any other Commonwealth territory. And Tasmania isn't even in Africa or India. I think a best idea should be the unofficial animal of the island, the Tasmania lion (that's actually a marsupial). A specimen of this animal isn't found for decades, but maybe it isn't extinct. Using the bottle green, associated with the island, I came with this flag:
Using the "Australian pale":
A white border to contrast better, and red is also used to represent Tasmania. Being sincere, I still prefer my first design.
