woolly hales from the Riverina district of NSW in Australia.
Now home isn’t exactly a closely settled area, though we wouldn’t consider ourselves as isolated. Typically you find a siding with a grain silo spaced every 10-20 miles along the railway line which was built in the 1920s. As a condition of building the railway, the large grazing holdings along the line were subdivided and bringing an influx of small farmers with holdings of 2-3,000 acres. Consequently, some of these sidings develop into hamlets. One of these has the quaint name of Bunnaloo.
When I was in primary school at neighbouring Caldwell, about 14 miles away, Bunnaloo Public had almost 60 children. We were a bit overawed about a school that was big enough to have more than one classroom and two teachers. 
Populations in these districts have declined significantly since then. Caldwell has long since closed and Bunnaloo now has a population of 33, a fuel depot, wheat silos, a church, cricket ground, tennis courts, community centre and eleven houses and the primary school.
Anyhow, Bunnaloo Public School had a back-to celebration to mark 75 years of education in the district last week. When it came a roll call, it turned out that 10 ex pupils, now obviously aged in their 80s, out of the initial enrolment of just 18 , were able to attend the re-union. Now I reckon that’s a pretty remarkable achievement.
Anybody out there able to match or beat that?
