Task History

Big Brother Australia 13 Task History
Week	Day(s)	Task Description	Result
1	1	After the first three housemates entered the house, Big Brother requested that one of them enter the Diary Room. Daniel, who entered it, was given a secret mission to sneak out of the house undetected, with Big Brother providing him with an escape plan. He was also allowed to bring one housemate with him. If he successfully completes the task, he and the housemate that he brings would earn immunity from the first eviction.
	4	On Day 4, Melissa was given a secret mission to hide a lamb figurine in each of the rooms of the house. She was allowed to recruit one housemate to help her. If any of lambs are found, Melissa would fail the secret mission. If she succeeds, the house would earn a lamb roast dinner.
	6	On Day 6, Big Brother placed thousands of balloons in the house. Inside of eighteen of them were golden cinema tickets. If the housemates find a balloon with a ticket, Big Brother would award them a movie night.
2	9	On Day 9, the housemates had to participate in "Scary-Oke." Each housemate had to enter the Scary-Oke room one at a time and sing "Walking on Sunshine." Additionally, the housemates had to stick their bodies into a dark box with a creature or an object inside. If all of the housemates succeeded, the house would earn an espresso machine. However, if one housemate failed, the whole house would fail the task.
	11	On Day 11, Big Brother attempted to surprise the housemates by "throwing surprises" at them. Their goal was not to react to these surprises. If the housemates complete the task, they would earn a KFC feast.
	14-15	On Day 14, the housemates competed in a 24-hour shopping task. Big Brother added a faulty alarm system throughout the house. For the next 24 hours, the housemates had to deactivate the alarms when they rang. If they successfully deactivate the alarm in a certain amount of time, they would earn $10 for their weekly budget.	$220
4	23	On Day 23, two housemates selected by Big Brother, Sarah Jane and Tilly, had to complete a task in the "Panic Room" to escape punishment. Big Brother's walls were covered with numbers, and both of them had to find the sum of all of the numbers. If they fail to guess the correct number, all of the housemates would be chained together for the next 16 hours.
	25-26	On Day 25, Big Brother added a "money tree" to the background. Over the course of 24 hours, the leaves would gradually fall off of the tree. For every leaf caught, $20 would be added to the shopping budget. Only two housemates are allowed to be under the money tree at the same time.	$280
	25-26	On Day 25, Big Brother gave Daniel the opportunity to have a phone call with evicted housemate Nick. In order to do so, Daniel would have to sabotage the shopping by task by intentionally dropping every leaf during his catching shift. If he catches a leaf or if the housemates suspect his sabotage, he would fail the secret mission.
	27	On Day 27, the housemates had to board "Big Brother's Boat." They had to keep the boat afloat for five hours, with at least six housemates staying on the boat at a time. If they could successfully do so, they would earn a celebratory feast.
5	30	On Day 30, the panic room was once again open. Two housemates selected, Daniel and Sid, had to assemble a line of 2,000 dominoes on the panic room floor. They had to topple all of the dominoes after they are stacked in three hours or less. If they succeed, they would avoid punishment. However, if they fail, Big Brother would force two housemates to guard Big Brother's door for the entire night.
	32	For the shopping budget, the housemates were given a secret mission to prevent Tilly from taking as many steps as possible. The housemates were originally given $1,000 of shopping money. For everyone 1,000 steps of movement recorded, the housemates would lose $250. Additionally, if she becomes suspicious of the mission, the housemates would fail the secret mission.	$250
6	39	On Day 39, Big Brother gave the housemates a shopping budget. They had to correctly guess the amount of birds living in the house. However, throughout the day, Big Brother would add more birds to the house. If the housemates are within 100 birds of the correct answer, they would earn $500 for the shopping budget. If they are outside of the 100 bird margin, they would earn no shopping money and be on basic rations.
	41	On Day 41, Big Brother began Hell Week with boot camp. The housemates had to complete tasks around the house holding a sack of potatoes, obeying all of Big Brother's commands. If they all successfully did so throughout the whole entire day, they would earn wooden stakes and a bag of potatoes.
		On Day 41, Big Brother gave Daniel a secret mission. His bag of potatoes was switched out with a much lighter sack of balls. If the housemates realized that his bag was switched or become suspicious that he is involved in a secret mission, he would fail the task. However, if he succeeds in convincing the housemates, he would earn a steak and chips feast. In addition, Daniel was allowed to bring another housemate to the feast. He chose Adriana.
7	44	On Day 44, the housemates were given a panic room task. Throughout the day, two housemates would enter the panic room at a time. All of the housemates had to stay inside until Big Brother said otherwise. If a housemate left the Panic Room prematurely, the housemates would fail the task and be punished.
	46-47	From Days 46-47, the housemates, over the course of 24 hours, were given a shopping task. After an alarm sounds, a name would appear on the living room screen, and that housemate would have to lie down and strap themselves onto a wheel. The remaining housemates would have to begin spinning the wheel before the alarm stops. For every successful attempt to spin the wheel, the housemates would earn $10 for the shopping budget. However, if the housemates do not make it to the wheel in time or the housemate spun leaves the wheel before being told to do so, the housemates would not earn the shopping money.	$180
8	51	On Day 51, all housemates, excluding Daniel and Sarah Jane, had to cram inside of a small car for five hours for a road trip. If they successfully do so, they would avoid punishment from Big Brother.
	52	On Day 52, Big Brother gave Ari a secret mission. Over the course of 60 minutes, Ari had to have a meaningful conversation with each of the seven other housemates about a topic of Big Brother's choice. If he successfully does so without the other housemates noticing, everybody would receive a phone call from home. However, Big Brother later revealed that Ari's task was fake, and instead, gave the secret mission to Tilly. Tilly's secret mission was to avoid having a conversation with Ari. If she successfully did so, the housemates would receive a phone call from home.
