Set in 1917 in a small Australian outback town and against the backdrop of a nation at war, Let the Balloon Go is a poignant story of a boy and his family. Young John Sumner has contracted polio and wears a leg brace. He also suffers mild epilepsy. While his brothers fight in the war overseas, John fights a much more personal battle - the battle for his own freedom. His over-anxious mother is afraid to let him play games and climb trees like other children. But John makes a determined effort to break free of his mother's domination and to win respect as an individual. With best mate Wombat the dog in tow, he causes mischief about town and proves he is capable of high adventure. Along the way we meet the pompous Police Constable Baird, bumbling Acting Fire Chief Gifford, and the town eccentric, Major 'Tiddly' Fairleigh, all caught in hilariously comic situations. Based on the novel by world-renowned author Ivan Southall, this story of letting go is straight from the heart of Australia.
