THE multimillion-dollar sale of a Sovereign Islands mega mansion not only marks the top sale in the past week but the second highest for its street.

An interstate buyer splashed $5.28 million on the property at 16 Westminster Court, which settled earlier this week.

It was snapped up in an off-market deal through Jeffrey Sturgess and Colleen Brunt of Amir Mian Prestige Property Agents.

Mr Sturgess said they had been helping the buyers find a property in the area for the past few years.
