Trying to contact long-lost friends

CAN you help us? We are trying to contact old friends Fred and Janet Bagshaw, having lost contact after we migrated to New Zealand in 1984. At that time they owned a sports shop in, I believe, Seaside Road. They had three daughters - Sarah Kathy and Hazel. We will be visiting Eastbourne on July 17-18 and would love to catch up with them. Our address is 56 Thomas Thomsen Drive, Bundaberg Qld., 4670 Australia. email
