Allsopp started his professional football
career with Croydon City in the Victorian Premier League
competition, having been selected from the Victorian
Institute of Sport in 1995. Later that year he made his name
in the under-17 World Championship, where he was top scorer
with 5 goals, including one in Australia's 3-1 loss to
eventual runners-up Brazil. His performance opened the door
for his entrance into the Australian National Soccer League,
signing with South Melbourne. He stayed with the club until
1997, having scored 2 goals in his 20 appearances. Allsopp
represented Australia again, this time at under-20 level in
the 1997 FIFA World Youth Championship in Malaysia, with
Australia making it through to the second round before being
knocked out by Japan. On his return he was signed for
Carlton SC, but was loaned out to VPL club Port Melbourne
Sharks.
Allsopp then moved to England to trial for Second
Division club Manchester City, and after scoring in City's
first friendly match against Newquay as well as some reserve
team matches, he was signed for the club for the 1998–99
season. Allsopp's 4 goals in 25 games saw Manchester City
promoted to the First Division, but he struggled to find a
regular place in the team as the team in the 1999–2000
season, and was loaned out to Notts County F.C.. Meanwhile,
Allsopp had become a regular member of Australia's under-23
national team (the "Olyroos") in 1999, and played 3 matches
for 1 goal in 2000, but was not selected in the squad for
the 2000 Summer Olympics. He was loaned to Wrexham A.F.C. in
early 2000, and scored 4 goals in just 3 league matches by
end of the 1999–2000 season. The following season he went on
loan to Bristol Rovers, where he failed to score a goal in
his 4 league appearances. Allsopp returned on loan to Notts
County, and scored 4 goals in 3 matches before being bought
for £300,000 by the club. In a 3-season career, he scored at
the impressive rate of 50 goals in 111 appearances (in all
matches) before signing with Hull City for 2003–04. The move
provided more success for Allsopp, as he scored 15 goals in
his first season and 7 in 2004–05 as a regular in the
line-up.
Allsopp negotiated an early release from Hull, and
decided to return to Australia to play for new club
Melbourne Victory under Ernie Merrick, who had coached
Allsopp during his time at the VIS. Despite making 20 starts
in the 2005–06 season, Allsopp was not nearly as prolific as
at his previous clubs, and only managed 3 goals for the
year. The season featured Allsopp's 250th match in all
league competitions, and he will remain with the Victory for
2006–07.
