International Tartan Day is observed on July 01, 2018. Three million Australians are either Scottish or of Scottish descent. International Tartan Day in Australia and New Zealand is celebrated on a local basis in most states on July 1 (or by some community organizations on the nearest Sunday), the anniversary of the Repeal Proclamation of 1782 annulling the Act of Proscription of 1747, which had made wearing tartan an offense punishable with up to seven years' transportation.
According to Scottish House secretary Moyna Scotland, the tendency to disguise Scottish associations was mirrored in Australia: 'Scots did what they were told to do when they came to Australia assimilate and integrate and they almost disappeared', and consequently one aim of Tartan Day is to help Australians reconnect with their Scottish ancestry. A tartan revival started in 1822, and Queensland and Australia have their own tartans. (With material from: Wikipedia)
