A teenager accused of stealing $2 million from Suncorp Bank in an online fraud had a bid for freedom refused.

Philip John Heggie, 19, was arrested almost a year ago after he tried to withdraw money erroneously deposited into a bank account he set up under a false name.

He was allowed bail on the condition he not use the internet but months later he was back in court after police discovered he was behind several fraudulent eBay accounts.

It is alleged he had ripped off eBay customers for $40,000 by selling non-existent goods using false identities.

Mr Heggie was denied further bail and has been in custody for almost nine months.

He faces about 200 fraud-related charges and almost 100 breach of bail charges.

In Brisbane Supreme Court today, his lawyers argued he should get bail because he was at risk of serving more time behind bars than he would receive when sentenced.

Barrister Ruth O'Gorman said her client had realised how serious his offending was.

"He says time has well and truly taught him a lesson," she said.

He would be committed to a condition of bail not to use the internet other than for university studies, she said.

He could live with his father at Eight Mile Plains in Brisbane's south and his mother could provide a $5000 surety.

Kathryn Adams, for the Crown, opposed Mr Heggie's bail, arguing he had already demonstrated a willingness to break his bail conditions.

Justice Ann Lyons refused bail, saying Mr Heggie was accused of "serious conduct, persistent and blatant offending".
