First Encounters and 'Terra Nullius'

Students learn best when they confront uncomfortable truths with evidence they can see and feel. This topic demands active engagement because it asks students to challenge long-held myths about colonization and land ownership. By analyzing maps, diaries, and oral histories, students move from abstract ideas to concrete realities, making the consequences of 'terra nullius' tangible.

Activity 01

• Jigsaw
• 50 min · Small Groups

Jigsaw: Multiple Perspectives

Divide class into expert groups, each studying one viewpoint: European explorer, First Nations elder, or colonial official. Experts prepare key quotes and facts, then regroup to teach peers and discuss terra nullius claims. Conclude with a class chart of shared insights.

Analyze the concept of 'terra nullius' and its devastating implications for First Nations peoples.

Facilitation Tip

During the Jigsaw activity, assign each group a distinct source type (explorer diaries, Indigenous oral histories, early maps) to ensure varied perspectives are represented before discussion.

What to look for

Pose the question: 'Imagine you are a First Nations person in 1788 and a British settler arrives claiming the land is empty. How would you explain your connection to this Country and why is the settler's claim wrong?' Facilitate a class discussion where students share their responses, focusing on empathy and understanding different perspectives.

Activity 02

• Socratic Seminar
• 40 min · Pairs

Role-Play: First Contact Scenarios

Assign pairs roles from historical encounters, using props like maps and journals. Pairs improvise dialogues highlighting terra nullius assumptions, then debrief in whole class on power imbalances and real impacts. Record key phrases for a class display.

Explain the immediate impacts of European arrival on Aboriginal land and culture.

Facilitation Tip

When running the Role-Play activity, provide clear role cards with historical context so students can stay grounded in evidence rather than improvising inaccurately.

What to look for

Provide students with a short primary source excerpt from either a settler's diary or an Indigenous oral history about first encounters. Ask them to identify one word or phrase that reveals the author's perspective on the land and explain why they chose it.

Activity 03

• Socratic Seminar
• 45 min · Small Groups

Timeline Stations: Before and After

Set up stations with pre- and post-contact images, artifacts, and texts. Small groups add events to a shared timeline, noting terra nullius effects on land use. Rotate stations and vote on most significant changes.

Critique the historical justifications for colonial expansion into Indigenous territories.

Facilitation Tip

At Timeline Stations, place a large annotated map at each station so students can physically track changes over time, reinforcing the impact of land seizures.

What to look for

On an exit ticket, ask students to define 'terra nullius' in their own words and list two specific consequences this concept had for First Nations peoples.

Debate Circles: Justifying Expansion

Form inner and outer circles; inner debates pros and cons of terra nullius using evidence cards, outer observes and switches in. Facilitate with prompts on Indigenous consequences, ending in consensus statements.

Analyze the concept of 'terra nullius' and its devastating implications for First Nations peoples.

Facilitation Tip

In Debate Circles, limit each student to one speaking turn to ensure quieter voices are heard and participation is balanced.

What to look for

Pose the question: 'Imagine you are a First Nations person in 1788 and a British settler arrives claiming the land is empty. How would you explain your connection to this Country and why is the settler's claim wrong?'

A few notes on teaching this unit

Experienced teachers approach this topic by centering Indigenous voices and knowledge systems from the start. Avoid framing colonization as inevitable; instead, highlight the deliberate legal and cultural erasures that allowed it to happen. Research shows that primary sources, especially Indigenous accounts, help students see 'terra nullius' as a tool of dispossession rather than a neutral description. Role-plays and debates work best when students have time to process emotions before discussing, so build in reflection moments.

Successful learning looks like students questioning sources critically, recognizing the complexity of first encounters, and articulating how legal constructs like 'terra nullius' erased Indigenous sovereignty. They should move beyond memorizing dates to explaining why perspectives matter and how power shaped outcomes. Evidence-based discussions and role-plays show their understanding is deep, not surface-level.

Watch Out for These Misconceptions

• During Jigsaw: Multiple Perspectives, watch for students assuming 'terra nullius' was an honest mistake rather than a legal fiction.

  Use the Indigenous source group’s map with place names and stories to directly contradict the settler source group’s claim of empty land. Have students compare the two maps side-by-side and ask, 'Which one shows prior occupation more clearly? Why might the British claim to have seen an empty land?'

• During Role-Play: First Contact Scenarios, watch for students minimizing conflict or portraying interactions as equal exchanges.

  After the role-play, debrief by asking each group to list one moment where power imbalance became visible. Then, compare these moments to primary source excerpts to highlight how violence and coercion were often downplayed in settler accounts.

• During Debate Circles: Justifying Expansion, watch for students repeating 'terra nullius' as a justification without engaging with Indigenous perspectives.

  Require students to reference at least one oral history or map from the Jigsaw activity in their arguments. Ask, 'How would a First Nations person respond to this claim? Use evidence from our sources to explain.'
