In 1840, droughts in other Australian colonies increased the cost of living rapidly because South Australia had not been self-sufficient for food yet. Gawler increased public expenditure but eventually the economy broke and the management policy of the colony was forced to change. Over £200,000 had been spent and the land fund in London had been exhausted. A £155,000 loan was approved by the British Parliament (later made a gift) and Captain George Grey was sent to replace Gawler.
