If you started school in Queensland in the late 1950s (as I did) then you would have sat at a desk just like this - one equipped with slates and slate pencils. You would almost certainly have carried a school 'port' like that on your back when you walked to school and it would have had a pencil case just like that nestled beside a sponge in a bottle of water and cleaning rag (for wiping your slate) and vegemite sandwiches wrapped in reusable greaseproof paper. You would not have waved a plastic Aussie flag like that but you would have stood on parade each morning and put your hand over your heart as you looked at the flag and recited "I love my God, I serve my Queen and Country, I honour the flag and I shall cheerfully obey my country's laws". Then you would have stood to attention as the national anthem God Save the Queen was played before marching in line to your school room -- I think we were still very regimented from the war years.
I had a lovely chat to the lady in the museum about the latest developments at the School of Distance Education which reaches out to children on remote properties. She also reminded me that Charters Towers has a strong continuing tradition of boarding schools catering to children from remote rural properties.
