Australian sperm floods UK

Australian travellers are turning the tables on the Brits, colonising the UK by stealth.

London fertility clinics have reported that up to a third of sperm donors are now foreigners, and many are visitors from Down Under.

Australians backpacking through the UK are among the biggest sperm donors in London.

One of the capital's biggest clinics, the Bridge Centre, confirmed Australian backpackers were becoming donors to gain extra money to support their travels.

"What you get with the 'grand tour' is very enterprising people who look at every single way of making a buck," spokesman Tim Mott said.

With an official report yesterday warning that donor numbers in Britain were critically low, the clinics are hoping more travelling Aussies will lend a hand.
