The total fees to bridge your cryptocurrencies from Ethereum to Optimism on Synapse are $15 - $20AUD. On most major exchanges this fee ranges from $30AUD to $50AUD. You can also get this figure lower if you change your bridging token to one with positive slippage like gOHM which only incurs a small $2AUD fee.
