It may be taken as characteristic of the painter's craft in Australia that the excessive heat and sudden changes of temperature, which open and close the wood, are much more destructive to his work than the more temperate climate of England. Burning off is therefore more frequently resorted to, and dark colours avoided for outside work; white, stone, and the general range of sienna colours alone being of the class that really withstand the excessive heat.

The bleaching effect of strong sunlight has also to be reckoned with when colour is used either externally or internally, and this leads to frequent renewal of the work should transient colours be employed.

The best English and Scotch white leads and materials still command the market in the best practice, though colouring earths, oxides, and white leads are all produced in a limited quantity in Australia.

For glazing, Australians generally prefer large sheet glass, though coloured leaded glass finds much favour for special purposes.

In Queensland and those tropical zones visited by heavy hailstorms, skylights of all kinds have to be strictly avoided, and it is not infrequent for the ice to be so strong and cutting as to completely perforate and honeycomb ordinary galvanised iron roofing.

For skylights in the Southern States, heavy glass with wire bedded in has been found to be the best, such a combination avoiding the accumulation of dust, which is an element to be reckoned with in all Australian towns.
