Australia's lowest-paid workers will receive a bigger pay rise than last year after the Fair Work Commission decided on an $18.80-a-week wage increase to $772 per week. However, many workers will not see immediate benefit.

SDA National Secretary, Gerard Dwyer and other Unions are expressing dismay that retail workers will have to wait another two months to receive any increase in their pay packets.

General retail award workers will have to wait until the first of September for a wage bump, while workers covered under aviation, fitness, tourism and certain retail sector awards will have their pay rise delayed until the first of November.
