Feb 23 (Reuters) - Australia's top fuel retailer Ampol ALD.AX posted an 83% rise in annual profit on Monday, helped by strong refiner margins at its Lytton refinery and a robust performance from its convenience retail operations.

The company reported net profit after tax from continuing operations of A$429.2 million ($303.92 million) on a replacement cost basis for the year ended December 31, compared with A$234.8 million a year earlier.

That compares with a Visible Alpha consensus estimate of A$428.47 million.
