Infrastructure and contract mining group Aveng has reported higher gross earnings of A$69.4-million for the six months ended December 31, compared with the prior half-year’s gross earnings of A$38.3-million. Interim group CEO David Simpson says revenue was, however, lower at A$1.2-billion, compared with revenue of A$1.4-billion in the prior comparable six months, owing to an anticipated slowdown in infrastructure activity in Australia and New Zealand.
