The Reserve Bank of Australia has unveiled the design of the new $10, and Australia has reacted as only Australia can — with parody.

The $10 note pays homage through symbolism to Dame Mary Gilmore and AB ‘Banjo’ Paterson, two celebrated Australian writers synonymous with Australian heritage.

It incorporates the same top-to-bottom clear window as the $5 note, a clear patch with a rolling-colour effect, and a “tactile” feature to help the vision-impaired community distinguish between denominations.

But, predictably, social media had a field day with its reaction to, and ‘analysis’ of the new note.

One particular wag tweeted the fact that Banjo Paterson’s poetry was still present, but had just been moved onto the poet’s collar.

However, on closer inspection, it’s clear that Banjo Paterson’s image had actually been ‘rickrolled’ — that is, pranked using the lyrics of pop singer Rick Astley’s 1987 hit, Never Gonna Give You Up.

The tweet was retweeted in serious fashion by a major media outlet, before they were alerted by a keen-eyed journalist at The Huffington Post.

The notes also incorporate Australiana illustrations such as a horseman, which points to Paterson’s classic poem The Man From Snowy River.

Each banknote in the new series will feature a different species of native Australian wattle and bird.

The $10 note features the bramble wattle and the sulphur-crested cockatoo.

Innovative new security features, such as complex holograms and areas that are only visible under UV light, have also been incorporated in the new $10 banknote to help keep them secure from counterfeiting.

The RBA has been working closely with various parties in recent years to ensure that the new banknotes can be used in typical day-to-day transactions across the country, including in machines that take or dispense banknotes.

Although the new $10 banknotes will be issued in September, it may take some time for them to be widely circulated.

The existing series of banknotes can continue to be used as all previously issued banknotes remain legal tender.
