Alternative pov that may help your snobbery: There is not yet an Australian English standard; it is just British. Therefore, Australians are free to create our own standard using parts of the existing standards or innovations of our own.
In particular, you are not propagating our own tradition by strictly adhering to so-called Australian spellings, which are really British spellings. On the contrary, you are declaring linguistic subordination. At this stage, the best option is tolerance of diversity, not snobbery.
If you look at an American book that has an edition produced by an Australia publisher, it may have American spellings, but most Australian editions (i.e. British editions, since their publishers claim Australia as a dependency) use British spelling.
