Australia's retail spending rose in November, a new private sector survey shows, despite major retailers complaining of weakening demand.

The Commonwealth Bank (CBA) Business Sales indicator (BSI) rose by 0.3 percent in trend terms in November, following on from similar rises in October and September.

The BSI, which tracks the value of credit and debit card transactions processed through CBA's point-of-sale terminals, recorded rises in spending in all states.
