‘Alston’, a stately trophy estate in one of the most sought-after riverfront addresses on the Gold Coast, is set to go under the hammer next month.

A national marketing campaign by Kollosche principal and sales agent Michael Kollosche, in conjunction with Rebecca Moffrey, has highlighted the extensive attributes of the landmark tri-level mansion at 5 McMillan Court within the prestigious Southport School precinct.

The trophy estate will be auctioned on site on Friday, 22 September at 5pm. In adherence with Queensland auction rules, no price guide has been disclosed and any prices previously associated with the property should be disregarded.

A strong desire to divest the asset and make a move to the beachfront led the seller to switch to an auction campaign and they are highly motivated to transact stating that “the property will be sold”. Any reasonable offer put forward prior to or on auction day will be considered.

Occupying a rare 3,442m2 allotment on Main River, the estate, designed by architect Michael Witty, holds an easterly aspect that capitalises on a stunning city backdrop with views across a wide expanse of water from Broadbeach to Main Beach.

The five-bedroom, seven-bathroom European-style home covers 2,451m2 of floor space, with a five-car secure basement garage, an indoor pool, gymnasium, sauna, bar, billiards room, cinema and a self-contained caretaker’s residence among some of the highlights. Outside, a private sandy beach and deep-water pontoon open up access to the Gold Coast waterways.

The high-profile auction follows hot on the heels of the recent successful sale of waterfront mansion 59 The Corso, Surfers Paradise, by sales agents Sam Guo, Julia Kuo, Claire Dai and Michael Kollosche.

The property, which was built in the late 1990s and requires a significant renovation, attracted 10 registered bidders and was snapped up under the hammer last month for $24,000,000.

The extraordinary result shows the appetite for prestige Gold Coast real estate – and the nine bidders who missed out on 59 The Corso are potentially still hunting a prized property.
