Well, we have Australia Day on the 26th of January (commemorating the arrival of the first fleet). This is a public holiday (meaning people get the day off work and school). Traditionally, families and friends will get together for a BBQ (preferably by the swimming pool). In recent years, Australia Day has become the subject of some controversy, as some in the Aboriginal community refer to it as "Invasion Day"

We also commemorate (not celebrate) Anzac Day on the 25th of April.
This is a day when we remember those soldiers and nurses who have given their lives in the line of duty during war (in particular World War 1). Anzac stands for Australian New Zealand Army Corps, and is observed in both countries. It is also observed at Gallipoli in Turkey, where many of the Anzacs are buried.
Tranditional observances would be attending a dawn service, followed by a march through the streets (soldiers, veterans and school children), followed by another service. (This is one rare occasion where Australia's Christian heritage is un-ashamedly shown. A Christian chaplain will openly pray and may read scripture.) The gambling game "two-up" can be legally played on Anzac day, but no other day of the year. We also eat Anzac buscuits (according to a simple recipe that soldiers could cook while out on the front)

(NOTE: When we say buscuit, we mean a cookie.)

We also have Remembrance Day, where we hold a minute silence to remember fallen soliders at 11:00AM on the 11th of November.
That's about it, really, for uniquely Aussie holidays. We have the usual Easter and Christmas, obviously.
