That snazzy blue new car he is leaning on is a 1962 Chrysler Valiant S Series.
Parked behind it is a Ford Falcon XK, which had its model run around the same
time, from 1960-62. Both model cars are in 1:43 scale, and both are made by
the Australian model manufacturer, Trax.
All through the 1950s, the General Motors company, Holden, ruled the roost in the Australian car market, but the early 60s saw the introduction of the American-designed and locally built Falcons and Valiants to spice up the market, especially for family-sized cars with straight six engines. Holden remained the top-selling brand for many more years to come (until Toyota knocked them off that perch much later on, but that's another story) but Falcons and Valiants quickly earned respect as well-made cars able to handle tough Australian conditions, and won many loyal fans as a result.
This Trax model of the Valiant is a lot nicer than the Trax model of the
Falcon, simply because it's a more recent production, and their
standards of manufacturing have improved over the years.
I was pleased, however, to get this plainish bluey-green Falcon, as I do
remember having a large (probably 1:24 scale) plastic toy model of this
car, in this colour, as a kid, given to me by a neighbor who worked for Ford.
Of course, being a kid I played with it endlessly, probably broke bits off it,
grew tired of it, tossed it into a box somewhere, forgot about it and Mum
probably gave it the coup de grace many years later, in a rubbish clean-up day.
