I do not think so. Power kerosine was referred to in the UK as Tractor Vaporising Oil, and it has a wikipedia entry - says the octane was 55-70.
This does not necessarily transfer to Australian conditions though. UK crude oil has mostly come from the Middle East, and is high in aromatics, where Australian crude imports have historically come from the Far East and North America, and would have been mostly paraffinic. The final composition of any product is constrained by its crude source.
Lighting kerosine has always been legally constrained to have a maximum flash point, which means lighter fractions must be removed, and market constrained to have not too much heavies, as these would make the flame smoky, and low sulphur, as this stinks. But octane rating was never even a consideration.
Power kerosine in Australia would have been basically the same fraction as lighting kerosine, but with less restriction on heavies, and with enough octane enhancers (probably branched hydrocarbons or aromatics) added as needed to raise the octane to about the figures quoted for TVO. Lighter fractions would not have been added, as they would have enabled the Power Kerosine to start from cold in many cars - and the idea was to restrict its use to tractors, which were set up with two tanks.
Worth noting that the first plane I owned (with a Gipsy major engine) was placarded for 70 octane.
Another note on octane - About 1916 the compression ratio of the Ford T engine was reduced (from about 5.0 to 3.98) as changes in oil sources reduced the average octane rating of petrol in the USA. Not that they knew about octane rating at the time - it was only just being explored by Harry Ricardo in England at the time, and while possible, it is unlikely that Ford would have heard of the work that early. When the US entered WW1 in 1917, one of the first things they did for the war effort was to supply tankerloads of petrol. Which, being lower octane wreaked havoc with Allied aeroplane engines in particular.
The British got their own back in WW2 when Middle East sourced fuel, high in aromatics, dissolved the self sealing lining of fuel tanks in US aircraft.
