I have always thought Australian Customs officers were a bit rude in the past but never as bad as returning to Melbourne Airport recently. it was a jolt to the system after experiencing helpful, welcoming and polite service from customs in China, Laos and Vietnam. It was a busy time of the morning and all traveler's had endured long overnight flights. Nearly all the customs officials were rude, heavy handed and bellowing smart allec remarks as they moved passengers along like cattle. In particular they were very abrupt and rude to foreign visitors, yelling at them in fast colloquial English which would have been difficult or impossible for anyone who did not speak very good English to understand. They showed absolutely no sensitivity or graciousness to foreign visitors in marked contrast to how Australians are received by customs in Asia. No wonder Australia gets a bad press in Asia. The customs officers behaviour and lack of respect confirms all the negative perceptions they read about this country. Why can't they be a little more sensitive and welcoming especially when first impressions count for so much? I and other travelers were disgusted by their behaviour.
