The buildings that make up the Customs Precinct are listed on the Queensland Heritage Register and the Fraser Coast Regional Council Local Heritage Register.
Maryborough’s Bond Store appears to be the oldest surviving in Queensland and the second-oldest surviving purpose-built government bond store in Australia. Given the Customs House and Residence also remain existent, Maryborough’s Customs Precinct is highly significant due to its rarity, intactness, and the fact that it is a comparatively early example of a customs complex in Australia.
