- History
In 1606, Willem Janszoon made the first recorded European landfall on the Australian continent (Australia).
- Geography
Dutch navigators reached Australia from 1606 and charted a large part of the coast over the following decades. They saw no commercial prospect, which is why the eventual colonisation was British.

1 × 1,000 + 6 × 100 + 6 × 1 = 1,606. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
2 corner wedges + 6 vertical wedges (sixties place), 4 corner wedges + 6 vertical wedges (units place)
26 × 60 + 46 = 1606. Places are separated by a space on the tablet, with the higher place written first.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
