MAJESTIC sea views, private beach, peaceful location... and all yours for a few million quid.

No, it's not another Sandbanks mansion coming on the market. This investment would get you far more for your millions.

It may not quite be the Caribbean or South Pacific, but Long Island, one of Poole Harbour's five main islands, is up for sale.

Agents Stephen Noble are listening to offers in excess of £1 million, though nearby Green Island sold for upwards of £4m in 2005.

Within 24 hours of coming on the market, the 31-acre island had already attracted feverish interest, and celebrity names are expected to join the likely bidding war.

Nigel Still, director at Stephen Noble, said: "It's an unbelievable opportunity for someone to purchase a most idyllic spot in the harbour.

"Before Green Island, an island had not been for sale in the harbour for 20 years, and Long Island has not been available for decades and decades.

"So the chances of another island coming up are remote.

"Green Island attracted celebrity interest and we believe Long Island will follow the same route."

Long Island is part of the Rempstone Estate, owned by the Ryder family, and has been in the family since the 1800s.

They have elected to sell after deciding the island was not being used to its full potential.

A designated Site of Special Scientific Interest (SSSI), it is described as a nature paradise, with its combination of salt marsh, woodland, cliffs and beaches.

It is home to an abundance of birds, as well as the rare red squirrel.

The only buildings on Long Island were built in World War Two and have since been dismantled.

Mr Still said the island was not being sold with building in mind and that any suggested development would be subject to planning consent.

Green Island is now owned by Edward Iliffie, son of publishing magnate Lord Iliffie, after he and his family purchased the plot in 2005.

Round Island, closest to Long Island, is owned by Broadstone builder Harry J Palmer, who bought it in the 1970s.

Furzey Island is now owned by BP for oil extraction, while the harbour's largest island, Brownsea, is maintained by the National Trust.

Mr Still said a bidding war for Long Island was "inevitable" and that they expected to finalise a deal within "four to six weeks".
