This landmark map is the first published record of the discoveries made by the Dutch ship "Dufken" on route to Cape York in Australia.
New Guinea ("Landt vande Papuos") is marked  the (Is)land next to it is called ÔNieu ZeelandtÕ and the island Duyfkens is named after the ship ÔDuyfkenÕ.
With the first publication of this map 27 years had passed since the voyage of the Dufken and its discoveries of PNG and NW Australia had been completed. The Dutch East India Company had suppressed the discoveries until it was sure how profitable or not Australia would be.

When Jansson & Hondius first published this map in 1630 it is believed the information was leaked from the Blaeu firm - the official cartographers to the Dutch East India Company - and surprisingly Blaeu did not publish a similar map for another two years. It must have been galling for Blaeu to have known of the discoveries for nearly thirty years and be beaten to publication by his fiercest rival Jansson & Hondius.
This is an incredibly significant map for the SE Asia, PNG and Australian region being the first published with real first hand knowledge which before had been mostly speculation or second hand knowledge. (Ref: Suarez; Koeman; M&B; Tooley)
