Australia is not at present planning to change its flag, although it is nice to dream. Although Australia is a member of the Commonwealth of nations, not all member states have the union jack on their flag. For example: Canada, Zimbabwe, India, South Africa, Nauru, and Ireland.
But I must admit, I HATE the bloody tea towel in the corner of our present flag. I do like the top small flag above though.
Fighting for the glory of the Australian Republic.
