"Oxfam Australia’s Board has made the difficult decision to close Oxfam Australia Trading amid ongoing commercial pressures and a tough retail environment," the non-governmental aid organisation's chief operating officer Tony McKimmie said.

"Declining revenue and profitability, including flat online sales growth, means the financially responsible decision is to close all Oxfam Australia Trading operations."
