He won four qualifying round matches to appear in the last 128 at the 1995 International Open, but there his progress was halted by a 2–5 defeat to Yasin Merchant of India.

In his second season on the main tour, he improved his personal best performance, recording five victories in the 1995 Grand prix before losing 3–5 in the last 96 to Mark King.

He was invited to participate in the 1996 Malta Masters, a sixteen-man event, where he won his first match 4–3 against Tony Drago, but Martin Dziewialtowski beat him 4–1 in their quarter-final.

However, he beat Shaun Murphy 6–4 in the final of Event 4 of the UK Tour in 1998 to secure his immediate return, and at the 1999 Welsh Open, he recorded a last-16 finish for the first time in his career.

Wallace beat Mark Miller, Wayne Brown, Quinten Hann, Ken Doherty, and Tony Chappel, and held James Wattana to 2–2 before losing 2–5.

Drawn to play his friend and fellow countryman Joe Swail, this match proved a tighter affair; Wallace led 6–2 and 7–4 but could not prevent an 11–13 loss.
