RSL Australia will review its Welcome to Country guidelines after Indigenous elders and veterans were booed during Anzac Day services across the country.Military leaders and politicians were quick to criticise the behaviour at commemorations in Melbourne, Perth and Sydney, with one person charged over a disturbance at the latter dawn service.Opposition leader Angus Taylor condemned the booing, but said he understood why some were concerned about Welcome to Country overuse.RSL national president Peter Tinley on Monday said he had been "appalled" by the behaviour at some Anzac Day ceremonies.He said he believed Welcome to Country had a place on Anzac Day, but said the decision to perform the address should fall to individual branches."What happens in far north Queensland or in far north Western Australia, they are localised choices," he said."They have to have a nose to the atmosphere that they’re working in, but we will show leadership.Mr Tinley said those who took issue with Welcome to Country addresses on Anzac Day appeared to be in the minority."My 20-year-old son, who is a third-year student at the defence academy in the army, his generation don’t have a problem with it," he said."It can get overworked .. I should have been able to be there without being booed," she said.Mr Tinley said RSL Australia would be seeking advice from the federal government to prevent further disruptions.He said Anzac Day commemorations had evolved over time, with orders of service "not cast in stone"."I think that's a good thing, to be dynamic and responsive and reflective to our community," he said."I think it's an opportunity for the RSL to reflect on it and come up with a way that actually makes it even more relevant and show leadership."
