Service Bus Namespace not visible in Azure Portal

Hi, I've created a service bus namespace using Azure Powershell using the following command:

New-AzureSBNamespace –Name SBTest -Location "North Europe" -CreateACSNamespace $true -NamespaceType Messaging

 I can then see this namespace is created using Get-AzureSBNamespace.

My problem is that this namespace then doesn't appear in the Azure Portal.  I've looked in All Resources and in Service Bus.  Am I missing something?

Thanks.
