The popularity of overseas property TV programmes in the UK could be behind growing investment interest in the Australian market, a website has said.

South Australia in particular is proving popular with investors because of its fine wines, festivals and hot weather, according to Landlord Expert.

Even though Australia is far very away from the UK, investors are finding the price, quality and promise of strong rental yields down under extremely attractive.

Ben Howard, director of Monopoly Realty Holdings, said: "The official rental property vacancy rates in South Australia are now hovering between 0.5 per cent and one per cent.

"Team this with the British pound providing excellent exchange values and many UK investors like the prospects of an Aussie residential investment."

Mr Howard added that many experts are predicting rents to increase by 20 per cent over the next three months.

According to Amberlamb, rental prices in all major Australian cities make any buy-to-let investment "immediately profitable".
