Cosplay Props & Replica Weapons: Convention and Airport Rules

What are the prop rules at San Diego Comic-Con?

Comic-Con International’s 2026 cosplay guidance says costume props are inspected at dedicated props desks and approved props receive a tag that must stay visible during the event. Functional or sharp-edged weapons are not allowed, replica projectile props must be disabled and capped with brightly coloured tips, real arrows must have their tips removed and be zip-tied to a quiver, and some props may need to be tied so they cannot be drawn. Realistic first-responder or security cosplay is also not permitted.

What about Australian conventions like Supanova?

Supanova’s cosplay guidelines and weapons policy remind attendees that they have a duty of care not to put others at risk, and that state law and venue rules decide which props are permitted. The policy asks cosplayers to think about crowded halls and whether a prop could hurt someone if dropped or swung, and props are checked by the event’s weapons-check team. Always read the latest policy for your event and city before you go.

Can I fly with a cosplay prop?

The U.S. Transportation Security Administration (TSA) says realistic replica weapons are not permitted through the security checkpoint, and recommends packing items such as replica swords, axes and scythes in checked bags to avoid delays. Replica explosives such as grenades are not allowed in carry-on or checked bags. TSA officers will treat a prop as real until they confirm otherwise, which can slow you down or lead to a fine. Use the TSA’s “What Can I Bring?” tool for specific items, and check your airline and destination country too.

Are replica weapons restricted in Australia?

Yes, some are. Under Australia’s Customs (Prohibited Imports) Regulations, many weapons can only be imported with permission, and the Australian Border Force says imitation firearms – a broad category that can include ornaments and toys – also need approval before import. State and territory laws also control carrying certain items in public. Check the official guidance for your item and state before you order or travel.

How do I make my prop convention-ready?

• Choose lightweight foam, PU or resin props over metal where possible.
• Remove or blunt any sharp edges and points.
• Use bright orange tips on blaster props where the event requires them.
• Carry props in a bag between photo spots, especially in crowds and on public transport.
• Arrive early so you have time for the weapons check.

Frequently asked questions

Can I take a replica sword in my carry-on bag?

No. The TSA says realistic replica weapons are not allowed through the checkpoint and recommends packing replica swords and similar props in checked luggage. Replica explosives are banned in both. Check your airline and local rules before you fly.

Will my prop be checked at a convention?

Usually yes. Large conventions such as San Diego Comic-Con inspect and tag costume props, and Australian events like Supanova run a weapons check for props.

Can I import a replica weapon into Australia?

Some weapons and replicas are prohibited or restricted imports into Australia. Check the Australian Border Force prohibited goods list for your item before ordering or travelling.
