Oster began his career with Grimsby Town, and he later played for Everton, Sunderland, Barnsley, Leeds United, Burnley, Reading, Crystal Palace, Doncaster Rovers, Barnet. He signed for current club Gateshead in September 2013.
Born in England, Oster represented Wales at international level, where he earned 13 caps between 1997 and 2004.
Oster started his career at Grimsby Town.
Oster moved to Sunderland for a fee in excess of £1 million. While with the club he was involved in an incident that ended the career of reserve player Mark Maley by accidentally shooting him in the eye with an air rifle. While at Sunderland, during the 2002–2003 season, he spent five months back on loan with his former club Grimsby Town. Oster was released by Sunderland in January 2005, shortly after returning to the Black Cats in disgrace from a loan at Leeds United, where he scored once against Millwall.
Oster made his debut for Reading against Brighton & Hove Albion on 9 August 2005 as a substitute. In January 2007, he extended his contract at the Madejski Stadium until the summer of 2008. He notched his first Premier League goal in nearly 10 years against Middlesbrough at the Riverside Stadium where the Royals were defeated for the first time in 2007, 2–1. After a couple of years as a squad player with the Royals, including a number of Premier League sub appearances, he was released by Reading following their relegation from the Premier League, on 16 May 2008.
Before signing for Crystal Palace, Oster had a trial spell at Championship rivals Derby County. Oster signed an initial six-month contract for Crystal Palace on 11 August 2008, which was extended by a further 18 months. He scored on his debut against Hereford United in the League Cup.
On 20 September 2013, Oster signed for Conference Premier club Gateshead on non-contract terms, the move being his first into Non-league. He made his debut the following day as a second half substitute against Tamworth. He scored his first goal for Gateshead on 21 December 2013 in a 2–4 defeat at Luton Town.
In April 2002 whilst at Sunderland, Oster accidentally shot reserve team player Mark Maley with an air-gun. Neither of the pair believed the gun was loaded and Maley had to undergo an eye operation. Whilst on loan at Leeds United in December 2004 Oster and Jamie McMaster were suspended by the club for misbehaving at the club's Christmas party. The incident spelled the end of his Leeds career and his loan was terminated.
