I had analyzed RNASeq data using R Programming Bioconductor packages (EdgeR, and DESEQ) along with FastQC, Trim_Galore, Kallisto. It was challenging to get access to servers and learn Linux.

Most of these tools are available on Galaxy (probably on Australia Galaxy) and you can drag and drop the tools to construct a workflow. Once workflow is built, customize the parameters on UI and execute the workflow

May I know what is Galaxy Australia 

Galaxy is a web based, click and run data analysis platform to execute tools and workflows. Galaxy Australia is a server hosting Galaxy platform, maintained by this team based on Australia.

and how it has advantages over other pipelines?

Galaxy Australia or Galaxy it self is not a pipeline. It's a data analysis framework. Compared to other frameworks (esp NGS data analysis), learning curve is minimal with Galaxy server for creating, editing and executing workflows. It's advantages are drag and drop building of workflows, visual editing of workflows, sharing with users, export the workflow and history. In addition, user can search, import and execute workflows shared by community members within Galaxy.
