Things to Consider When Buying a Bed in Australia
Bedding Compatibility: If you’re moving from another country, be aware that your existing sheets, blankets, and mattress protectors might not fit Australian beds perfectly.
Mattress Availability: While some international sizes may be available, most retailers in Australia will stock Australian-standard sizes.
Cost Considerations: Importing a mattress of non-standard dimensions can be expensive, so buying locally is often easier.

Whether you’re bringing a mattress from abroad or planning to buy it locally, knowing these variations can help you make the right choice. If you’re moving to Australia, it’s usually best to stick with local sizes to avoid compatibility issues with bedding and frames.
