It is impossible to precisely judge the value of money in the past, yet some idea is necessary to make sense of lives. Therefore, we do give conversions to modern values but emphasise that these must be treated as, at best, rough estimates. For Australian currency from 1850-1900, we use Thom Blake's converter, converting amounts to roughly equivalent 2015 values. For more on estimating the value of past money, see his query.php. For the value of money from 1901, we rely on the Reserve Bank of Australia's https://www.rba.gov.au/calculator/annualPreDecimal.html
