Table, telescope in Sydney Airport auction

Sydney Airport is set to auction off its yearly batch of lost luggage which includes a glass table, a telescope and even a violin.

Nearly 5000 items will go up for sale in nine online auctions beginning next Tuesday, with proceeds being shared between charities for children, conservation and Lifeline Australia.

"Some of the weird and wonderful things people have left at the airport include a drill, glass table, microwave, mountain bike, pram, telescope and tools," the airport's managing director Kerrie Mather said in a statement on Thursday.

Aside from the unusual lost property, there is a bundle of electrical goods such as smartphones, tablets and cameras.

Last year's auction raised a record $234,000 and the airport hoping this year's will beat that figure.

People can browse and test out items at the airport from Monday and bids begin at $1.
