Melodramas tend to be formulaic productions, with a clearly constructed world of connotations: a villain poses a threat, the hero escapes the threat (or rescues the heroine) and there is (generally) a happy ending.
So who doesn't want to see a story like this after all the ones about failed lives that resemble reality a little too closely? Those movies are usually too preachy anyhow. This movie is full of good looking people who kiss and ride horses and shoot guns and in the end seem to be going towards their happily ever after. So go see it. It's a good thing.
This review summarized my feelings on the film pretty well. Here's a snip-it:
"And then, from the graphic beauty of the opening credits to the bigger than the Outback story line, Baz had me at G'day. All the most popular of fictions swirling around its epic story: improbable love, class differences, larger than life characters, incredible landscape, life and death. And, my favorite story technique, an omniscient narrator speaking from some time in the future about the past that you are viewing. A movie with highs and lows, tensions built and equitably satisfied, a soaring score, a major throwback, stirring, Hollywood epic.
I just reread that paragraph and I hope it entices you to go see Australia, but, I realized I hadn't even mentioned cattle drives, bar fights, war, violence, mystery, love unrequited, love requited. It is such a big movie that at one point, halfway in, I fully expected a dissolve to a 'Intermission' sign and cocktails in the lobby discussing what we had all just seen and then back in for the climax. Australia feels like one of those big road show movies of the fifties: Ben-Hur, Cleopatra, The Ten Commandments, The Longest Day."
And here's a trailer if you don't even know what I'm talking about:
