A man allegedly gained access to a 62-year-old man's superannuation account and withdrew $120,000, Queensland Police say.

A 35-year-old man is expected to face the Cleveland Magistrates Court later on Wednesday charged with one count of fraud and one count of dealing with identification particulars.

Police allege he withdrew large sums of money from the fund and the victim, from Logan, south of Brisbane, only noticed when he couldn't access the account.

Police didn't say how the man's account was accessed, but Detective Superintendent Brian Hay said scams like it can occur through old-fashioned mail theft.

Det Supt Hay said people should consider electing to receive their bank statements online, but he warned them to be wary of other scams.

"Do not respond to emails from banks or funds requesting you update your password or details and go the extra mile and do further checks when contacted by your institution," he said in a statement.
