Have maintained a steady speed of about 25 knots in fine weather. It is however, colder & tomorrow we go back into ‘blues’ for our arrival at Fremantle, which should be at about 1030. Yesterday, action stations were held to exercise breakdowns. The ECP seems very exposed after the comparative security of B turret. Position at Midday Friday was 18°28’S, 101° 55’E & Saturday, 26° 00’S, 108° 07’E.
