What was sir john robertson's main fear about federation?

Sir John Robertson's main fear about federation was that it would undermine the autonomy of the individual Australian colonies and lead to an over-centralized government. He was particularly concerned that the interests of smaller colonies would be overshadowed by larger ones, resulting in a loss of local control and representation. Additionally, Robertson believed that federation could exacerbate divisions between rural and urban interests, ultimately harming the agricultural economy of New South Wales, which he championed.
