International representative rowing
Parker made his first Australian representative appearance in 1995 in the stroke seat of a quad scull which competed at the 1995 Nations Cup in Groningen and finished in eight place.. That same crew went to the 1995 Junior World Rowing Championships in Poznan where the entire Australian squad was affected by food poisoning at the regatta accommodation. That crew finished in thirteenth place. In 1995 he was selected in an Australian double-scull which contested a junior Trans-Tasman series against New Zealand crews. In 1996 he again contested the Trans Tasman junior challenge series in Sydney. In 1997 he was selected with Glen Loftus to row Australia's lightweight double scull at the U23 World Rowing Championships in Milan where they raced to a silver medal. He made his Australian senior representative debut in 1999 in a lightweight single scull at the World Rowing Cup III in Lucerne. That year he was also Australia's lightweight single sculler at the U23 World Championships in Hamburg where he won a gold medal and an U23 world championship title. He then was Australia's lightweight single sculling entrant at the 1999 World Rowing Championships in St Catharines, Canada where he missed the A final and rowed to an overall seventh place finish. In 2000 Parker moved into selection contention in sweep-oared boats. He was in the five seat of the Australian men's lightweight eight when they won gold at the World Rowing Cup III in Lucerne and the held his seat for the 2000 World Rowing Championships in Zagreb where the eight rowed to a bronze medal. Parker rowed on in both boat classes in 2001. With Dan Stewart he rowed a lightweight double scull to a fourth placing at the World Rowing Cup IV in Munich.
