While NSW tops the list for the highest value of lost and unclaimed super on a state basis, the top two postcodes are in Queensland: Mackay and surrounding areas with 13,338 accounts totalling $62.2 million, followed by Cairns and surrounding areas with 18,288 accounts totalling $61.4 million.

Taking out third place is Liverpool and surrounding areas in NSW, with 13,994 accounts totalling $59.1 million in lost and unclaimed super.

Interestingly, over half the amount of lost super held by super funds belongs to people aged 40 to 55.

ATO assistant commissioner Debbie Rawlings said that people should ensure they are keeping track of their super and combine their accounts if they have any lost or unclaimed super.

“Over the past four financial years we’ve reunited 1.68 million accounts worth $8.12 billion with the account owner, and there’s plenty more to be found,” Ms Rawlings said.

“These figures show there are many people who still may not realise how quickly and easily they can check their super accounts.”
