Black and white photograph of a group of five unknown men working with a very large concrete block. It may be that they are manoeuvring the block to tip it into the water. Newspaper reports in the Coffs Harbour and Dorrigo Advocate in 1928 and 1929 indicate that large concrete blocks were being used to construct the Eastern Breakwall down at the Jetty. An article on Tuesday, 20 March, 1928 page 2, under 'Coffs Harbour Improvements. Question of 100 ton blocks'  states, '... concrete blocks of 100 tons were tipped at the base of the eastern breakwater to stabilise the wall at a critical point, it is not practical, except at very great expense, to handle blocks of this size as the breakwater progresses in length.' However, a later article on Friday 13th July 1928, page 2 entitled 'Coffs Harbour Works' states, Mr Buttenshaw, minister for works, (who was passing through on a train to Grafton on Wednesday morning 11th July) and ' ... the ministerial party were just a minute too late to see one of the big concrete blocks being dumped on to the end of the eastern wall. It could be seen plainly from the railway station.' A further article on Tuesday 26 February 1929, page 2, entitled 'Coffs Harbour Works. New Reclamation Area Started', reports 90 big concrete blocks were made but required further machinery to install indicating they were '... ready to be tipped when the additional crane is completed and the rails laid.'
