Aug 18 (Reuters) - Australia's top fuel retailer Ampol ALD.AX posted a 23% fall in its first-half profit on Monday, hurt by supply chain disruptions that weighed on volumes and a drop in refinery margins at its key Lytton refinery.
Ampol's net profit after tax from continuing operations was A$180.2 million ($117.31 million) on a replacement-cost basis for the six-month ended June 30, compared with A$233.7 million a year ago.
That beat the Visible Alpha consensus estimate of A$165.6 million.
