Joann is from Hobart, and John originally from London. John migrated to Australia in 1971. Joann and John met in Perth in late-2017.
Joann has a house in Perth and John has one in Broome (2,200km apart) so this relationship involves a fair bit of travel! And that's not to mention the overseas holidays they both enjoy to destination like Vietnam and Thailand.
John has three fine children from his marriage with Carol (who passed away in 2017): Andrew (1974), Simon (1975) and Lisa (1978). There is more information about John and Carol and their children here.
