It was time for me to go diving again, so I betook myself to Christ­mas Island, this extern­al ter­rit­ory of Aus­tralia in the Indi­an Ocean. Under water I encountered sharks, dol­phins and oth­er creatures of the sea. Above water I went hik­ing, climb­ing and bird­watch­ing in hon­our of the words of someone very dear to me: ‘Take many pic­tures, do many things you don’t get to do in Singa­pore and remem­ber each and every one of them.’
