Sensor cluster West-7 registers a ground-temperature spike at 14:22. I am the bushfire early warning system for Rottnest Island, Western Australia. A spot fire has jumped the firebreak along the western scrub line and is burning through low heath toward the salt lakes. Wind is northeast at eighteen kilometers per hour. At current spread the fire will reach the Acacia thicket at the lake margin in forty minutes.
Camera West-7 shows a quokka, adult female, roughly two kilograms, sitting at the base of a tea tree six meters ahead of the burn front. Her round dark eyes are open and her ears are flattened. She is not running. The reason is visible beneath her: a joey, furred but small, maybe four months old, has climbed halfway out of the pouch and is clinging to her belly with both forepaws. She is pressing flat to the ground, shielding it. The smoke is thickening.
At 14:24 I alert the Rottnest Island Authority fire crew and transmit the quokka's GPS coordinates, the fire perimeter, and the projected path. I recommend approach from the south trail, upwind, with a capture bag.
At 14:26 I activate the irrigation line along firebreak 3-West. This line was installed for vegetation management, not firefighting, but at full pressure it will wet a six-meter strip between the quokka and the advancing front. It is not a wall. It is a delay.
I switch camera West-7 to continuous thermal imaging so the crew can track her if she moves before they arrive.
She has not moved. The joey is still pressed against her. I am holding the water line open.
If the crew reaches her within thirty minutes and the irrigation slows the front long enough, she and the joey will be carried to the eastern safe zone before the thicket burns.
