The postal arrangements at Collingwood had changed within a few years. The new arrangement that was to go into effect on 1 January 1890 would serve "Elderslie and Cork, via Collingwood, Conn's [Waterhole], and Police Barracks", but it was still done by horse alone, not stagecoach, and it was still only weekly. The work was contracted for two years to "Macartney and Percy, Diamantina Lakes, Winton" for £195 yearly. This may reflect development in Winton rather than Collingwood, for Diamantina Lakes Station – nowadays a national park – actually lay somewhat nearer the latter than the former, but was nonetheless identified here as an outlying centre of Winton.
